If your garbage disposal is not working, the first step is to identify the problem based on its symptoms. Is it humming but not spinning, or is it completely silent? Understanding the issue will guide you to the right solution. Always prioritize safety: never put your hand down the disposal, and always switch it off (and ideally unplug it or flip its breaker) before attempting any repairs.
### Diagnosing the Problem
#### Humming but Not Spinning
If your garbage disposal is humming but not spinning, it is likely jammed. This is a common issue and can be fixed with the following steps:
1. **Cut Power**: Ensure the disposal is switched off and unplugged or the breaker is flipped.
2. **Clear the Jam**: Insert the hex or Allen wrench into the socket on the underside of the disposal and turn it back and forth to free the flywheel. Alternatively, use the manual turning tool if your model has one.
3. **Remove Obstructions**: Once the flywheel is free, remove any objects that may be causing the jam.
#### Silent or Dead Disposal
A silent or dead garbage disposal indicates a loss of power or a tripped circuit. Follow these steps:
1. **Press the Reset Button**: Locate the red reset button on the bottom of the disposal and press it.
2. **Check Power Sources**: Ensure the wall switch is on, the outlet is working, and the breaker has not tripped.
3. **Inspect for Damage**: If the reset button does not work, there may be internal damage, and you should call a professional.
#### Leaking Disposal
A leaking garbage disposal can be due to several issues:
1. **Sink Flange**: If leaking from the top, the sink flange may be loose or damaged.
2. **Seals**: Leaking from the middle could indicate a problem with the seals.
3. **Shell Crack**: If leaking from the bottom, the shell may be cracked, and the disposal will need to be replaced.
#### Slow Drain or Clog
A slow drain or clog can be resolved by:
1. **Clearing the Obstruction**: Use a plunger or a plumber’s snake to remove the clog.
2. **Check for Build-up**: Run water and check for any build-up in the disposal.
### Troubleshooting Table
| Symptom | Likely Cause | Fix |
|---|---|---|
| Humming but not spinning | Jam | Clear with hex wrench, remove obstruction |
| Silent or dead | Loss of power, tripped circuit | Press reset button, check power sources |
| Leaking from top | Loose or damaged sink flange | Tighten or replace flange |
| Leaking from middle | Faulty seals | Replace seals |
| Leaking from bottom | Cracked shell | Replace disposal |
| Slow drain or clog | Obstruction or build-up | Clear with plunger or snake, check for build-up |
### When to Call a Professional
If you have tried the above steps and the garbage disposal is still not working, or if you are uncomfortable performing any of the repairs, it is best to call a licensed plumber or electrician. Additionally, if you suspect internal damage or a cracked shell, a professional should handle the replacement.
How to clear a jam safely
If your garbage disposal is not working, it may be jammed. Here’s how to clear a jam safely:
- Cut power: Always start by turning off the power at the switch and unplugging the disposal if possible. This is crucial for your safety.
- Use an Allen wrench: Locate the socket at the bottom of the disposal unit. Insert a 1/4-inch or 5/16-inch Allen wrench into the socket and move it back and forth to dislodge the jam.
- Rock the wrench: Gently rock the wrench back and forth until you feel the impeller move freely. This should help break up the jam.
- Remove debris: Use tongs or pliers to remove any debris that may be causing the jam. Never use your hands.
- Restore power: Once the jam is cleared, plug the disposal back in and turn the power back on at the switch.
- Press reset: If the disposal has a reset button, press it to restore normal operation.
Why it keeps tripping or humming
If your garbage disposal keeps tripping the circuit breaker or is making a humming noise, it could be due to several reasons:
- Repeated jams: Frequent jamming can cause the disposal to overheat and trip the circuit breaker. This could be due to trying to grind inappropriate items or a buildup of debris.
- Worn motor: Over time, the motor in the disposal can wear out. If the motor is struggling to turn the blades, it may hum and eventually trip the breaker. In this case, you may need to replace the disposal.
If the problem persists after clearing a jam, it may be time to consult a professional to inspect the motor and electrical components.
What not to put down a disposal
To prevent jams and prolong the life of your garbage disposal, avoid putting certain items down it. Here are some common items that should never go into a garbage disposal:
| Item | Reason |
|---|---|
| Grease | Greas can solidify and clog the disposal and pipes. |
| Fibrous peels | Peels from items like celery and asparagus can wrap around the blades. |
| Bones | Bones are too hard and can damage the blades. |
| Coffee grounds | Coffee grounds can accumulate and cause clogs. |
| Pits | Pits from fruits like peaches and avocados are too hard and can damage the disposal. |
Always follow the manufacturer’s guidelines for what can and cannot be put into your garbage disposal.
Garbage disposal leaking: where it’s coming from
If you notice water leaking from your garbage disposal, identifying the source of the leak is crucial for effective repair. Here’s a guide to help you pinpoint where the leak might be coming from:
- Top Leak: If the leak is at the top of the disposal, it is likely coming from the sink flange. The flange is the part that connects the disposal to the sink. Over time, the seal around the flange can deteriorate, causing leaks. To fix this, you may need to reseal the flange with plumber’s putty or replace the gasket.
- Middle Leak: A leak from the middle of the disposal could be due to a problem with the dishwasher hose or the seals around it. Check the hose connection and the seals for any signs of wear or damage. If the hose or seals are compromised, they will need to be replaced.
- Bottom Leak: If the leak is at the bottom of the disposal, it may indicate a cracked shell. This is a more serious issue and typically means that the disposal needs to be replaced. A cracked shell cannot be repaired and poses a risk of further leakage and potential electrical hazards.
Reset button vs circuit breaker
When your garbage disposal stops working, it can be helpful to understand the difference between the reset button and the circuit breaker, and how to troubleshoot each:
- Reset Button: The garbage disposal unit is equipped with a red reset button, usually located on the bottom of the unit. This button is a safety feature that trips when the disposal experiences an overload, such as jamming or overheating. If your disposal is not working, first check if the reset button has been tripped. Press the button in to reset the disposal. If it clicks in and stays in, try turning on the disposal again. If it trips again immediately, there may be a more serious issue that needs to be addressed.
- Circuit Breaker: The circuit breaker in your home’s electrical panel protects the circuit that powers the garbage disposal. If the reset button does not solve the problem, check the circuit breaker. Locate the appropriate breaker and ensure it has not been tripped. If it has, switch it back to the “on” position. Also, check the wall switch that controls the disposal to make sure it is in the “on” position. If the breaker continues to trip, there may be an electrical issue that requires the attention of a licensed electrician.
Always remember to cut power to the disposal before attempting any repairs, and consult the product labels for specific instructions. If you are unsure or uncomfortable with any part of the process, it is best to call a licensed professional to avoid potential hazards.
